Cornell University (2008, May 1). First Nanoscale Image Of Soil Reveals An 'Incredible' Variety, Rich With Patterns. ScienceDaily. Retrieved May 2, 2008 Citat: "...But when you look at soil's organic carbon closely, it has an incredible variety of known compounds..."None of these compounds that you can see on a nanoscale level looks anything close to the sum of the entire organic matter."...While the composition of organic carbon in soils from North America, Panama, Brazil, Kenya or New Zealand proved remarkably similar within each sample, the researchers found that within spaces separated by mere micrometers, soils from any of these locations showed striking variation in their compositions..."
